cIOS249 rev 14 normally comes with it's own installer app that you'd launch from homebrew channel. Wad manager is not required for this.
Bannerbomb won't do anything, it's just an exploit that runs a boot.elf file on your SD card.
Bootmii should be installed as boot2 if possible, if not then as IOS. You need to grab the hackmii installer to do that.
